Adult chronic non-bacterial osteitis (CNO): An illustrated CT-based radiological guideline.

Chronic non-bacterial osteitis (CNO) is a rare chronic auto-inflammatory bone disease. In adults, it primarily affects the axial skeleton, especially the anterior chest wall, followed by the spine and the mandible. Whole Body-MRI (WB-MRI) or computed tomography (CT) combined with nuclear imaging are the preferred imaging techniques for the diagnosis and monitoring of adult CNO.
